upgrade to a 5d?

I have been reading and reading and reading threads pertaining to this subject and now that my head has stopped hurting I figure I would add to the mess.

I am having a hard time deciding if I should upgrade from my 40d to a 5d (classic). My shooting style tends to be more on the urban/landscape/family & trying my hand at macro type photography. I also would like to start getting some action shots of my son and his friends on their skateboards.

1. Would I really benefit that much by going to the 5d?
2. I believe that my current lens lineup would work well on a 5d, correct?
3. Would the Tamron 17-50 work on a 5d? If not, what would be a comparable lens?

I am thinking that I would sell my 40d w/grip, the 28-135 IS and the Sigma 10-20 and use those funds to purchase a good used 5d.

Does this sound like a good plan? My budget is the $1000 range.

3) Tamron 17-50 will not work....28-75mm f/2.8 will though.....and it'll work really well
Used 5Dc will run you about 1k

Some people are able to make the 5D classic work for action shots. It may require more technique than does the 40D.

You ask whether or not you'll benefit that much by going to the 5D. You will if:

• You need even narrower depth of field than you can already get
  
• You shoot in dim light a lot, and find your 40D's low-light capabilities lacking (be sure you've exhausted your postprocessing options before deciding based on this)
  
• You're used to shooting film and your mind is attuned to 35mm
  

• General speed of the user interface
  
• Focus point coverage -- the 5D's focus points are all clustered near the center of the frame
  
• Off-center focus point flexibility -- the 5D's peripheral autofocus points are not cross-type like the 40D's are
  
• Reach (a teleconverter can be used to make up most of the difference, but only if the lens is f/4 or faster, and that's assuming you don't use the same teleconverter on the 40D)
  
• Rapid-fire speed -- the 40D is twice as fast as the 5D in terms of how quickly it can fire off frames (6 FPS versus 3)
  
• Certain in-camera processing features, e.g. highlight tone priority. Matters only if you don't shoot RAW
